Hidden Fights

The Hidden Fights in Mortal Kombat X are located in different Premier Living Towers. Discovering them will give you the Keep it Secret Achievement. The conditions for reaching these Fights are usually getting to a specific match in the Tower and winning the match with a specific type of a Finising move and/or getting a Flawless Victory.
To reach a specific hidden fight, its Tower must be available at the moment. There is a chance however that even with the right conditions, you might not activate the Hidden Fight so you will just have to keep on trying.

Hidden Reptile Fight / MK1 Premier Tower

Here is how to Activate the secret fight with Reptile and Get the Keep it Secret Achievement:

Reach the 6th battle from the Mortal Kombat 1 Living Tower (This means the Living Tower must be currently present)

Hidden Mileena Fight / MK3 Premier Tower

There is no specific requirement for activating the secret fight with Mileena in the Mortal Kombat 3 Premier Tower (as well as Getting the Keep it Secret Achievent with it), as it can be seen in this video below:

Hidden Mileena Fight / The Day of Love Premier Tower

Here is how to Activate the secret fight with Mileena in The Day of Love Premier Tower and Get the Keep it Secret Achievement. What makes this fight unique is that it includes the Kabal Assist modifier in the shape of small teddy bear that only Mileena can use. The teddy bear deals 35% damage and is very hard to see due to it's brown color blending with the Kove stage. This modifier is a reference to a Millena challenge from the Mortal Kombat 9 Challenge Tower mode.

Here is how to Activate the secret fight with Carl Weathers Jax in the Predator Troophy Hunter Premier Tower and get the Keep it Secret Achievement (keep in mind that this is a character-lock Tower, so you get only one chance at to reach that Hidden Fight, so if you fail, you have to re-play the Tower all over again):

The Krypt

The Krypt in Mortal Kombat X is the location where you can unlock hidden content from the game, including finishers, alternative outfits, concept art, sound tracks and much more. The Krypt is devided in several different locations and contains puzzles which you must solve in orders to access hidden areas. Some of the content is time locked and can only seen on a specific time which you can check by using the timer on the screen. Once the time is right, the coffin will show up at their chosen location and remain visible until the time runs out. For the first time in the Mortal Kombat history, the krypt can be unlocked by paying for it with real money in the console's store.
